SharkBite Lead-Free Push-to-Connect End Stop Fitting

The SharkBite End Stop is a push-to-connect fitting built to cap off copper, CPVC, or PEX tubing in any combination without soldering, clamps, unions, or glue. Available in trade sizes ranging from 3/8" (1/2" OD) to 1/2", it's a go-to solution for capping a line during pressure testing on a rough-in job, and unlike a soldered cap, this fitting is fully reusable. Rated to 200 PSI and 200°F, the lead-free (LF) construction is certified for potable water supply and hydronic heating applications, making it a dependable choice for plumbers who need a fast, code-appropriate way to shut down a line.

  • Pressure & Temperature Rating: Certified to 200 PSI and 200°F, suitable for pressure testing and hydronic heating lines.
  • Push-to-Connect Design: No soldering, clamps, unions, or glue required — simply insert the pipe to seal.

  • Reusable Connection: Disassembles quickly with a simple disconnect tool so the fitting can be removed and reused on future jobs.

SharkBite U514LF – Frequently Asked Questions

1) Can a SharkBite end stop cap a copper line without soldering?
Yes. The SharkBite push-to-connect end stop caps copper, CPVC, or PEX with no solder, glue, clamps, or unions. You push the tubing in, stainless steel grip teeth bite the pipe, and an O-ring compresses to seal it. That makes it workable on a wet line or in a spot where you can't get a torch in.
2) What sizes does the SharkBite end stop come in, and what does 3/8 inch (1/2 inch OD) mean?
Two trade sizes: 3/8 inch (1/2 inch OD), part number U512LF, and 1/2 inch, part number U514LF. The 3/8 inch designation is the copper trade size, which measures 1/2 inch on the outside diameter. Order by the trade size stamped on your tubing, not by a caliper reading of the OD.
3) Can I use a push-to-connect end stop to cap a line for a pressure test and then take it off?
That's one of its main uses. The end stop is rated to 200 PSI and 200 degrees F, so it holds a standard rough-in pressure test, and it comes off with a disconnect tool and goes back on another job. A soldered cap is a one-way trip; this one isn't.
4) Can I cap a PEX line with the same fitting I use on copper?
Yes, and that's the point of it. One end stop takes copper, CPVC, or PEX in any combination, so a mixed-material repair or retrofit doesn't need separate caps per material. No crimp ring or clamp tool needed on the PEX side.
5) Is the SharkBite end stop safe for potable water?
It's lead-free (LF) construction certified for potable water supply, and the catalog lists it to the No-Lead standard. It's also certified for hydronic heating applications, which is where the 200 degree F rating matters.
6) Will a push-to-connect end stop hold behind a wall, or should I solder instead?
The end stop is rated 200 PSI at 200 degrees F and is listed for behind-the-wall capping of copper, CPVC, or PEX, including hydronic line termination. Choose it when you want the cap reusable or can't use a torch. If the cap is permanent and the line is all copper in an accessible chase, a soldered cap is the cheaper consumable; the trade-off is you destroy it to reopen the line.
7) Do I need any tools to install or remove the SharkBite end stop?
Installing takes no tools, just push the tubing in to the stop. Removal takes a SharkBite disconnect tool or clip sized to the tubing, which is sold separately and is not included with the fitting. If you plan to pull the cap after a pressure test, have the right size disconnect tool on hand.
8) Can the fitting be turned after it's pushed on?
It rotates after assembly, which helps when you're capping a stub in a tight bay or behind a fixture and need to clear something. The seal doesn't depend on orientation.
